Sažetak
Endocarp lignification is important fruit growth phenophase since after its completion fruit starts with oil accumulation. The information about duration of endocarp lignification is important for timing of management practices, irrigation and pest control in oil cultivars, and fruit thinning in table cultivars to obtain uniform fruit weight and size. In this study, fruit length, width and weight of four Istrian autochthonous olive cultivars (Buža, Puntoža, Rošinjola and Istarska bjelica) were measured. Samples were taken from olive collection orchard of the Institute of Agriculture and Tourism in Poreč in equal growing conditions. The aim of research was to define an olive fruit growth dynamics during pit hardening. Fruit weight in all cultivars was increasing during endocarp lignification (from 7th to 28th July). The highest percentage in the weight growth in the first week had cultivars Buža (48, 5%) and Rošinjola (44, 6%) and in the second week maximum was reached by cultivars Puntoža (44, 2%) and Istarska bjelica (42%). The highest increase in total fruit mass was detected at Puntoža (1, 30 g) and the least at Rošinjola (0, 56 g). Maximum increase in length (L) and width (W) had Puntoža (L: 7, 13mm ; W: 4, 23mm) and the least Istarska bjelica (L: 2, 48mm ; W: 2, 70mm).
